For me he has to much overweight and it looks ok but maybe less would be better. In General i must say overalls are for everyone and not every guy is small and thin.But for the guys who have a bit more, i would choose some baggy overalls. Be proud and wear what you want!

I see you holding those bibs up with your hands. 😖 That's why overalls have straps. If you wear both the straps, your baggy overalls won't fall off of your body. You will look so much better when everyone can see the whole bib on your chest.
